A method of editing a routing table managing network connections to a plurality of network interfaces in an image forming system includes receiving a user request for a change in network settings between the plurality of network interfaces defined in the routing table and networks, editing the defined network settings based on the received user request, and updating the routing table based on the edited network settings.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An image forming system to manage network connections to a plurality of network interfaces by using a routing table, the image forming system comprising: an image forming apparatus including a routing table management unit; and a host device to provide a user interface for controlling the routing table management unit of the image forming apparatus according to a user request and for displaying information about network settings included in the routing table stored in the image forming apparatus, wherein the host device receives the user request for a change in the network settings between networks and the plurality of network interfaces defined by the routing table through the user interface, wherein the received user request comprises information on a network address to be added to the routing table, and wherein the routing table management unit of the image forming apparatus attempts a connection to the network address through the plurality of network interfaces, edits the defined network settings of the routing table with a network interface connectible to the network address based on a result of the attempting the connection, and updates the routing table based on the edited network settings.
2. The image forming system of claim 1 , wherein the network address comprises information about at least one of an Internet protocol (IP) address, a port number, and a communication protocol.
3. The image forming system of claim 1 , wherein the image forming apparatus edits the defined network settings by mapping the network interface of the plurality of network interfaces connectible to the network address.
4. The image forming system of claim 3 , wherein the connectible network interface is a default gateway corresponding to the network address.
5. The image forming system of claim 1 , wherein the routing table management unit of the image forming apparatus comprises: a connection control unit to attempt a connection to the network address through the plurality of network interfaces; and a route acquisition unit to acquire information about a network route connectible to the network address based on a result of the attempting the connection, wherein the image forming apparatus edits the routing table based on the acquired information about the network route.
6. The image forming system of claim 5 , wherein the host device receives a network route to be connected from a user after providing the user with the information about the network route, wherein the image forming apparatus edits the routing table based on the network route.
7. The image forming system of claim 5 , wherein, if the information about the network route comprises a plurality of network routes, the host device provides a user with the plurality of network routes by arranging the plurality of network routes according to a number of hosts to be included in each network route.
8. The image forming system of claim 5 , wherein the connection control unit attempts the connection to the network address by using at least one of a ping test, a transmission control protocol(TCP)/IP test, a connection test according to a traceroute command, and a connection test based on a communication protocol with respect to each network interface.
9. The image forming system of claim 1 , wherein the received user request comprises a user request for a network setting to be corrected or deleted by a user with respect to the routing table.
10. A method of editing a routing table managing network connections to a plurality of network interfaces in an image forming system, the method comprising: providing, by a host device, a user interface for controlling a routing table management unit of an image forming apparatus according to a user request and for displaying information about network settings included in the routing table stored in the image forming apparatus; receiving, by the image forming apparatus, the user request from the host device for a change in the network settings between networks and the plurality of network interfaces defined by the routing table through the user interface, wherein the received user request comprises information on a network address to be added to the routing table; attempting, by the routing table management unit of the image forming apparatus, a connection to the network address through the plurality of network interfaces; editing, by the routing table management unit of the image forming apparatus, the defined network settings of the routing table with a network interface connectible to the network address based on a result of the attempting the connection; and updating, by the routing table management unit of the image forming apparatus, the routing table based on the edited network settings.
11. The method of claim 10 , wherein the editing of the defined network settings comprises editing the defined network settings by mapping the network interface of the plurality of network interfaces connectible to the network address.
12. The method of claim 10 , wherein the editing of the defined network settings comprises: acquiring information about a network route connectible to the network address based on a result of the attempting of the connection; and editing the routing table based on the acquired information about the network route.
13. The method of claim 12 , further comprising: providing a user with the information about the network route through the user interface; and receiving a network route to be connected from the user through the user interface, wherein the editing of the defined network settings comprises editing the routing table based on the network route.
14. The method of claim 10 , wherein the received user request comprises a user request for a network setting to be corrected or deleted by a user with respect to the routing table.
15. A non-transitory computer-readable recording medium storing a program to implement the method of claim 10 .
